WINTER 2017 McWANE DUCTILE PROJECT PROFILES Pg.10 Pg. 6 McWane New Hires Pg. 18 Ask the Ditch Doctor INSIDE CANADA'S FASTEST McWane Ductile GROWING COMMUNITY (PG. 4) IN THIS ISSUE WELCOME TO MODERN McWANE Dear Readers, and when you want to build your utilities to last for generations, your best choice is Ductile Iron Pipe from McWane Ductile. Another issue of Modern McWane is here for your enjoyment. Being Again, we also want to bring up to you the continuing lobbying the Winter Issue, it brings the by the American Chemistry Council and the PVC pipe industry thoughts of endings and beginnings to restrict what you choose to put into your utility system. They to mind. Holiday decorations are again pushing legislation to have state governments and are put up, taken down and put federal agencies require utilities to include PVC in all project away. Friends, new additions to specifications. This is in spite of increasing research raising our families, and coworkers are the question of the potential negative health effects of plastics, welcomed, and those who have passed are remembered and especially PVC. It has been shown that the production of PVC missed. As a song’s lyrics go, “Every new beginning comes from in particular creates toxins that are dangerous enough to make some other beginning’s end.” As 2017 ends, we reflect on the communities uninhabitable. Is PVC the lead and asbestos of the past year and begin preparing for the upcoming year. Reviews 21st century has yet to be answered, but being responsible for and evaluations are done, initiatives are identified and created, the public health of the people who rely on these utility systems planning meetings are held, and expectations are set. we build, can the risk be accepted?

STRINGER, MANAGER, ONTARIO SALES REGION THE PROJECT Britannia Rd. — Halton Region (Milton), Ontario 2016/17 Contract S-2977A -15 Vol. 2A Triple Sewage Force Main / Microtunnel Carrier Pipe Ductile Iron Pipe — 450mm dia.

The municipality deemed Britannia Road to be a major community. Situated only 40 km (25 miles) west of downtown east/west traffic route and did not wish to have the road Toronto, it offers more affordable housing in a combined closed for any length of time. urban/country setting. Census Canada has Milton as the “youngest people” town with an average age of 34 years. THE PROPOSAL Rapid urban sprawl precipitates various growing pains, in 1. The original pipeline design included a bridgecrossing (single servicing rural land. Planning departments have many items pipeline) back to a triple pipeline for future, using about 40% to deal with, especially the treatment and supply of safe, microtunnelling on other sections of the pipeline. fresh drinking water and the collection and treatment of raw sewage and wastewater. When sewage and wastewater 2. Ward & Burke would later propose doing the entire force cannot flow by gravity, it must be pumped. The Britannia main (95%) through microtunnelling. This would permit a Road forcemain would involve pumping raw sewage from a triple pipeline throughout (no reduction to a single pipeline huge pumping station a distance of 1,000 metres to overcome along the bridge). underground obstacles and negative slopes. 3. Via a series of launch shafts, a triple pipe assembly would be drawn through 1500 mm diameter concrete tunnel pipe. THE CHALLENGES 4. This triple pipe assembly would need to be the strongest 1. Sewage pumping dynamics would require that three available pipe material with integral pipe-joint restraint. 450 mm (18”) pipelines together would be utilized to pump The pipe would need to withstand the push and pulling sewage to a gravity location. Because the optimum volume forces required for the assembled triple pipeline lengths would increase over time, one larger diameter pipe would and potential surge pressure from pump start-up and not be suitable. Three pipelines would also provide backup instantaneous velocity change (power failure). pumping capacity and the ability to service pumps and equipment while remaining fully operational. Connections in the shafts (directional change) would also require restrained mechanical joint fittings to tighten on the 2. Obstacles along the route included existing natural gas and pipe, and lastly, the annulus between the triple pipe assembly fiber-optic lines, a creek ravine with bridge, and of course, and the casing would be grouted with concrete, including the negative slope. shaft piping connections. 4 *Inside diameters of Ductile Iron Pipe are larger than the stated nominal size. This will equate to large energy (pumping) cost savings over time. THE OUTCOME 1. Ward & Burke paid great attention to detail from the very beginning. 2. A system was carefully put into place that would carry throughout the project. Pipe joint integrity, leading to a good water seal, would be paramount in every step of the installation. 3. The triple TR Flex® Ductile Iron Pipeline was pressure tested in two long sections, at 170 psi. 4. 100% test results, no leaks (there just couldn’t be). 5. Complete triple pipeline grouted in concrete, including KEY/CRITICAL shafts. Ductile Iron Pipe has strong resistance, where possible collapsing could occur (no problem here). 1. A joint leak in any of the 3,000 meters (1,000 x 3) was unthinkable. This would involve the removal of the entire 6. The tunnelling contractor and all parties involved were triple pipe assembly only to start over again. extremely pleased with TR Flex® Ductile Iron Pipe and its unrivalled advantages/characteristics. 2.
